Intelligent electric drill with speed and function mode recognition

Abstract

An intelligent electric drill includes a case which has an MCU control unit, a drive unit, a power unit, and a data unit. The MCU control unit controls the power, speed, and torque of the drive unit. A mechanical speed mode recognition module group is electrically connected to the MCU control unit and includes a speed mode recognition electronic module and a plastic speed mode module within the case. The mechanical speed mode recognition module group determines the switching position of the plastic speed mode module, and the speed mode recognition electronic module inputs the determined signal to the MCU control unit. This allows users to automatically recognize the positions of mechanical speed mode and function mode while driving with the electric drill. Users can drive with accurate and appropriate power, achieving precise output of speed, torque, and workload.
